okhp3-murderbird-hook-and-close

Forge and stress-test the opening line and closing line of a short post (LinkedIn, X, Threads, Bluesky, Discord) so the hook earns attention honestly and the close lands hard on the point. Returns scored hook and close options with a pick. Use when a short draft exists and the owner asks to sharpen the hook, fix the ending, or "make it land". Not for full drafting, angle mining, or publishing.
